查询词典 algorithm theory

Packet classification is a technique to match each incoming packet at a muter against a database of classifier and specify forwarding rules for the packets. The classifiers are a powerful and uniform way to implement new network services. The study on IP packet classification algorithm has practical significance and theory value.
